# Migration from W5100S

## Question

Asked by Daan on 2019-02-25 in Ethernet Chips.

We are using the W5100S with the WIZnet library. How big would the impact be, regarding the software, if we would migrate to the W6100?

Hi Daan

W5100s can’t migrate W6100 about software.
They use a different iolibrary, and register name / address is also different.
They can migrate about only hardware.

thanks,
best regards,
irina
